The game is essentially a series of 36 jigsaw puzzles with Tetris-like pieces known as pentominos
that must be assembled into a specific shape. The puzzles start off
simple, with the shapes being comprised mostly of rectangles and having
simple solutions, but the puzzles quickly grow More complex, with odder
shapes like a rocketship, a gun, and even enlarged versions of some of
the pentominoes themselves. Each level is timed, and once the timer is
started it cannot be stopped until the level is finished. One starts
off the game with only three pentomino pieces, and at the completion of
each early level, a new piece is awarded to the player. At the final
level, the player is given the 2x2 square O tetromino and must complete an 8x8 square puzzle.
After completing each level, the player was given a password to
access that level at a later time. Interestingly, each password was a
common English four-letter word, so that by guessing common four-letter
words, players could potentially access levels they had not actually
reached by playing the game.
The name of the game was inspired by Daedalus, the mythical character of Greek legend who created the labyrinth.
